HOW TO MAKE MERMAID SLIME FOR UNDER THE SEA!

We definitely loved making our homemade ocean slime last time, so this time we thought about a mermaid slime instead! My son is particularly fond of the ocean and the beach and he has a great friend who is also fond of mermaids.

This slime has the beautiful glossy colors of the ocean with hints of purple and sparkle for the mermaid lover too. You can add seas glass, shells, colored or clear gems, and anything else to complete your under the sea theme.

This slime uses our sparkling glitter glue slime recipe, and you can find the link below. I couldn’t help myself with all the gorgeous photos I took while my son enjoyed the slime!

We ended up making a bunch of colors and they look amazing when they begin to swirl together. Plus it’s a lot of fun to play with a huge pile of homemade slime. You don’t half to make full size batches either to save on glue! Just make 1/2 the batch and split the ingredients in half.

Below you can see our container of ingredients before we added the starch! Look at all of the gorgeous color, sparkling glitter, and sequins!

Think about your favorite combinations for a mermaid with blues, greens, and purples. We also whipped up an iridescent batch to go along with the others.

The reaction between the ingredients will be felt immediately when you add the liquid starch. Your slime will start to form right away and will become more and more slime like {rubberier} as you mix and knead it. I usually end up doing the final mixing with my hands.

*ALWAYS WASH HANDS AFTER PLAYING WITH SLIME!*

Purples, blues, and greens with an additional iridescent batch of slime! You can see that we also added clear and colored gems picked up at the dollar store. Maybe you even have a plastic mermaid or fish to add to the slime activity.

SLIME RECIPE SCIENCE INFORMATION

Mix the colors, see how far it stretches, squeeze it, bounce it! Slime is an awesome tactile sensor experience, but did you know that it is also an awesome chemistry activity for cool science?

When you learn how to make mermaid slime you also have the opportunity to learn about polymers, cross linking, mixtures and more! Read more about the science behind the slime here.

A polymer glue is made up of tons of long, repeating, and identical chains of flexible molecules. When you add any of the borate ions to it {see below}, it helps to link those molecules together.

Normally those molecules slide past each other in a liquid form like when you are just using the glue to stick things down, but when you add one of these cross linkers to it, the molecules become thicker and thicker because they can no longer slide as easily.

The substance becomes more viscous and more rubbery the more the molecules start getting jumbled up thus resembling what we think of as slime. If you notice, the mixture also becomes larger than the liquids you started with in the beginning.

Check out what happens when you stretch out the slime. It looks like glass!

How long can you get the slime to stretch before it breaks in two pieces?
